Progress is reported on the development of a partial syntactic analysis technique for indexing text. Although over 500,000 words of text have been indexed, this report is limited to the analysis of results at the 115,000 word level. There is the expectation that the error rate of commission, the selection of grammatically incorrect word sequences, can be held to the 2 percent level. Dictionary growth is reasonable. Computer processing speeds are good. Original and revised indexing subroutines are provided. Appendixes provide samples of good index terms for each acceptable format in the format dictionary as well as samples of incorrect word sequences. (The progress report for the period January 1967-June 1969 is reported in ED 038159 and is available from NTIS as AD 696200.) (Author)
